2. DOS/Windows 3.x Two configuration software programs are provided with the SSP-200/300: a Client Driver, and a card Enabler. Both of these programs are executed from DOS (before entering Windows) and allow operation of the SSP-200/300 in both the DOS and Windows 3.x environments. For optimal operation, however, the Client Driver is the preferred method of installation and configuration. The table below highlights the differences between these programs.
2.1 SSP-200/300 Client Driver for DOS In order to use the SSP-200/300 Client Driver, the system must be configured with Card and Socket Services software. Card and Socket Services software is not provided with the SSP-200/300 but is available from Quatech. IMPORTANT: Some versions of Card and Socket Services dated before 1993 do not support general purpose I/O cards.
version of Card and Socket Services must be installed on the system or the SSP-200/300 Enabler program must be used to configure the adapter. If the Client Driver reports the desired adapter configuration, the installation process is complete and the SSP-200/300 may be removed and/ or inserted from the system as desired. On each insertion into the PCMCIA socket, the SSP-200/300 will be automatically reconfigured according to the command line options. 2.1.
Option o0 o1 o2 o3 Port Output Driver Always Enabled DTR Controlled RTS Controlled Auto-Toggle Figure 0. DOS Client Output Enable Options. H instructs the client driver to enable the RTS-CTS modem control handshake on the RS-422/485 port. When modem control handshaking in enabled, the 16C750 UART’s RTS and CTS signals are connected to the RS-422/485 auxiliary channel. The auxiliary channel may then be used for handshaking between the SSP-200/300’s port and a peripheral device.
2.1.2.3 Example 3 DEVICE = C:\SSP-200\SSP231CL.SYS(s0,b300,i5,o2) In example 3, a single command line argument is provided. The Client Driver will attempt to configure a SSP-200/300 inserted into socket 0 with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the SSP-200/300 will not be configured. In addition, if aSSP-200/300 is inserted into any other socket, it will not be configured.
2.1.2.6 Example 6 DEVICE = C:\SSP-200\SSP231CL.SYS (b300,i5) ( ) (i10) In example 6, the three command line arguments of example 5 have been rearranged. The Client Driver will first attempt to configure a SSP-200/300 inserted into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will proceed to the second command line argument and attempt to configure the card with a base address and IRQ assigned by Card and Socket Services.
Available Resources: One function of the Card and Socket Services software is to track which system resources (memory addresses, I/O addresses, IRQs, etc.) are available for assignment to inserted PCMCIA cards. Sometimes, however, the Card Services software assumes or incorrectly determines that a particular resource is used when it is actually available. Most Card and Socket Services generate a resource table in a file (typically in the form of an .
The SSP-200/300 Enabler does not support automatic configuration of adapters upon insertion, more commonly referred to as "Hot Swapping". This means the adapter must be installed in one of the system's PCMCIA sockets before executing SSP231EN.EXE. If more than one adapter is installed in a system, the Enabler must be executed separately for each adapter. Furthermore, SSP231EN.EXE should be executed to release the resources used by the adapter before it is removed from the PCMCIA socket.
Waddress specifies the base address of the memory window required to configure the SSP-200/300. Set address = D0 for a memory window at segment D000, address = D8 for a memory window at segment D800, etc. Valid settings for address are C8, CC, D0, D4, D8, and DC. If this option is omitted, a memory window at segment D000 will be used. Odriver specifies RS-422/485 output driver enable option for theSSP-200/300.
2.2.1.1 Example 1 SSP231EN.EXE In example 1, no command line argument is specified. The Enabler will report an error and display the proper usage of the command. 2.2.1.2 Example 2 SSP231EN.EXE (s0,b300,i5) In example 2, the Enabler will configure the SSP-200/300 in socket 0 with a base address of 300H and IRQ 5 using a configuration memory window at segment D000. The SSP-200/300 unit's RS-422/485 output drivers will always be enabled, and RTS-CTS modem control handshaking will be disabled. 2.2.1.
2.2.1.6 Example 6 SSP231EN.EXE (s0,b300,i5,r) In example 6, the Enabler will release the configuration used by the SSP-200/300 in socket 0 using a configuration memory window at segment D000. The base address and IRQ parameters are ignored and may be omitted. 2.2.1.7 Example 7 SSP231EN.EXE (s1,r,wcc) In example 7, the Enabler will release the configuration used by the SSP-200/300 in socket 1 using a configuration memory window at segment CC00. 2.2.
For systems configured with Card and Socket Services, the SSP-200/300 Client Driver is the recommended method of configuration. 2-13 SSP-200/300 (Rev.

5 Windows NT 5.1 Installing SSP-200/300 To allow easy configuration of the SSP-200/300 the Quatech Device Manager for Windows NT has been written for the hardware. This configuration utility supports the SSP-200/300 only in block addressing mode. To begin the installation, open Windows Explorer and search for the ‘Setup.exe’ command to install the Quatech Device Manager. (D:\Serial Port Adapters\Drivers\Windows NT 4.0 for PCI, PCMCIA,ISA).
1. Locate and double click the Quatech Device Manager icon on the desktop Device Manager Icon on Desktop 5-2 SSP-200/300 (Rev.
2. Click the ‘Add’ button at the bottom of the Quatech Device Manager Window 3. Follow the steps for the ‘Add Quatech Hardware Wizard’.
4. Complete the final steps of the installation, shut down Windows NT and then insert the PCMCIA Card and re-boot the computer. Additional help is available online The SSP-200/300 PC Card should now be configured. In the future, Windows NT will automatically recognize and configure the SSP-200/300. Note: Windows NT does not support ‘Plug and Play’ for PCMCIA cards. The PCMCIA Card must be inserted prior to starting Windows NT and can not be removed and reinserted while Windows NT is running.
6. Hardware Information 6.1 Auxiliary Channel Configuration An auxiliary channel is provided which allows for handshaking between the SSP-200/300 port and a peripheral device. This auxiliary channel may be configured in one of two ways: v RTS-CTS handshake enabled. v handshaking is disabled. 6.1.1 Auxiliary Channel: RTS-CTS Handshaking. The RTS-CTS handshake may be enabled so that RTS (request to send) is the auxiliary output signal on AUX OUT+ (pin 1) and AUX OUT- (pin 6).
6.1.2 Auxiliary Channel: Handshaking Disabled. The SSP-200/300 ports may be configured so that the RTS-CTS handshake is disabled. This is the default configuration. In this configuration, RTS and CTS from the 16C750 UART will be looped back to each other. In addition, the auxiliary output and input signals will be looped back to each other.
6.2 Half Duplex Operation The SSP-200/300’s ports may be configured for either full duplex or half duplex operation. By default, the RS-422/485 ports are configured for full duplex operation with the RS-422/485 output drivers always enabled. In half duplex mode, the RS-422/485 transmitter may be enabled and disabled via the RTS (request to send) or DTR (data terminal ready) signals. Both RTS and DTR are controlled through the Modem Control Register of the 16750.
Selection of half duplex mode operation is dependent upon the configuration software and/or the operating system used. Each of these, however, ultimately control the half duplex mode by accessing the PCMCIA Configuration Register on the SSP-200/300. CAUTION: When operating in half duplex mode, the transmitter output drivers must be disabled before receiving any information.
6.3 Termination Resistors No termination resistors are provided on the SSP-200/300 ports. Both output and input signals are connected only to the external connector. Any termination which is required must be added externally. RS-422/485 Receiver RXD+ + Rt - RXD- RS-422/485 Receiver AUXIN+ + Rt - AUXIN- Recommended Termination Resistor Values RS-422 100 ohm 1/2W resistor RS-485 60 ohms total resistance (120 ohms at each end) Figure 0.
